BOILER-SKIIVL'MEB.

Application filed October 1 T 0 all whom it may concern.

Be it known that we, Noi-usnnr SOHREIBER and RAPHAEL fiosmzrnaii,citizens of the United States, residing at Lincoln, in the county ofLogan and tate of Illinois, have invented a certain new and usefulImprovement in Boiler-fikimmers, of which the following is a full,clear, concise, and exact description, reference being had to theaccompanying drawings, forming a part of this specification.

Our invention relates to boiler skimmers for skimming or taking off thescum or refuse matter on top of the water in the boiler.

Prominent objects of the invention are to provide a simple and practicalconstruction of device of the class mentioned; to simplify the same,reducing the number of parts to a minimum and making the constructioninexpensive; to provide simple and expeditious means for withdrawing anddisposing of the skimmed matter; to provide a form of deviceparticularly adapted for use in locomotive boilers; to arrange for theadvantageous use of the skimmed matter in assisting the traction effortsof the locomotive; and to secure the foregoing and other desirableresults in a simple and expeditious manner.

In carrying out our invention in the manner herein set forth, we providea suitable frame conveniently made of pipes or pipe sections connectedtogether and supported by attached floats, whereby said frame may easilyrest or float upon the surface of the water which is to be skimmed. .This frame has suitable apertures or openings to permit the entry into itof the skimmed matter which apertures or openings form a suitablesurface intake. A convenient arrangement is to have the sides of thepipes provided with apertures or openings in the form of circular holes,although of course this arran gement of surface intake could be varied.The floating frame is connected by a loose or movable connection with asuitable outlet pipe, whereby the skimmed matters may be withdrawn anddischarged.

As a further improvement the frame may be made of substantiallyrectangular and oblong form so as to fit into the rear upward portion ofa locomotive boiler, one end of the frame being elevated so as to passover the top of the dry pipe of the boiler, and the outlet or dischargeend of the device may be Patented 28, 1915.

conveniently connected with the throttle valve of the locomotive wherebythe dlscharge may be regulated by the throttle.

its a matter of further and specific imbe increased.

In the accompanying drawings Figure lis a plan of a boiler skimmerembodying our present invention; Fig. 2 is a side elevation of the same;Fig. 3 is an end elevation of the device; Fig. i is a view of a portionof a locomotive boiler showing our improved skimmer embodied therein;Fig. 5 is a horizontal section of a portion of the device showingcertain details of construction more fully.

Referring first to Figs. 1, 2 and 3, we snow a frame A. which ispreferably made of general rectangular form as shown in Fig. 1. Saidframe is desirably made of pipe sections as 1, 2, 3, ek and 55, sections5-5 being vertical and supporting the elevated sections which areconnected by coupling 6. The outer sides of the pipes l, and 3 arepreferablv rovided with apertures or openings 7 (Figs. 2 and 5), so asto provide a surface intake for the refuse or scum to be skimmed off thetop of the water.

l loats l010 are provided to support the frame A. Preferably four floats10 are employed, conveniently located at or about the corners of theframe A as shown in Fig. 1. These floats may be arranged or connected inany suitable way so as to support the frame A, a convenient arrangementbeing that shown in the drawings wherein side pipes 11-11 are providedand the floats 10 mounted upon them, each float having a threadedconnection, as shown at 12 with the pipe 11 whereby it may be adjustedwith reference to said pipe. The side pipes 11 are supported by smallcross pipes 14.1st connected to the main pipes 11. The floats 10 arepreferably elongated as shown in the drawings, whereby they may bearranged close to the frame A.

An outlet pipe 15 is connected by a T-shaped coupling 16 with the pipe2, the coupling 16 being preferably loose so as to give it a rotary orswivel connection with said pipe Said pipe 15 is connected at its otherend to another T 17 which is mounted loosely upon a short pipe section18 (Fig. 5) connected by a yoke 19 with a pipe .20. The coupling 17 isalso mounted for rotation or swivel movement upon the pipe section 18,whereby an up down movement of the frame A is permitted by the outletconnection 15, the ends of the pipe 18 being conveniently closed by plugcaps 21. The pipe 20 may be any suitable discharge pipe extended to anydesired locality to effect a proper discharge of the refuse matterskimmed from the top of the water.

The construction just described is particularly advantageous for use ina locomotive boiler and is so shown in Fig. i. In such case elevatedpipes t--it are located above the dry pipe of the locomotive, a portionof whose boiler 2% is shown in the drawings, the frame A being ofsuitable size to fit conveniently within the rear of said boiler, asshown. In this case the outlet pipe 20 is desirably extended back to therear of the locomotive and provided with a valve 25 having a link andlever connection 26 and 27 with the throttle lever 28, whereby thedischarge through the pipe 20 may be controlled by the throttle. Whenthe lever 28 is operated to open the throttle valve, the valve 25 isopened so as to ser nit a discharge from the skimmer and when the lever28 is operated to close the throttle, the valve 25 is also closed,whereby there is a continuous blow-off from the skimmer while the engineis running, or at least while it is receiving steam for operation.

As a matter of further improvement we show a supplemental discharge pipelead ing down almost to the track 30 on which the locomotive runsbetween the driving wheels thereof. In this way the refuse matter fromthe boiler may be discharged upon the track and so help the traction ofthe engine. The pipe 29 is preferably provided with a separate handvalve 31 by which discharge through said pipe 29 may be furthercontrolled.

It will be understood that changes and modifications may be made withoutdeparting from the spirit of the invention. It is also understood thatthe elevated pipes -'l4 are particularly intended for use in alocomotive boiler and that when tae device is used for other purposessaid end pipes would preferably not be elevated but would be in more orless the same plane with. the pipes 1, 2 and It will be seen that bymaking the device of pipe sections in this way great economy andexpediency in manufacture are secured, because no special fittings,casings or patterns are required, pipe sections of standard pipe beingused.
